I bring back from the Stax thread this SR-X/Mk3 repair case.
I took the plunge and opened the SR-X/Mk3 drivers. I mean, not just the earcups, but the drivers (diaphragm and stators).
I did it because the sound wasn't up to my expectations. My goal was (and still is) to clean inside and recoat the diaphragms.
My first surprises were :
1. Both diaphragms were firmly stuck to one stator. I mean stuck like glue...
2. There were small holes in the diaphragms
3. There's a kind of large foil ring that's missing in one driver, compared to the other.
Could you help me please.
I wouldn't bother to change the diaphragm if the holes are small. If you want to recoat the diaphragm, clean the diaphragm with alcohol or acetone. Make sure there is no dust on the surface. You only need to coat the the diaphragm one side. It's normal to see that the diaphragm is glued to one of the stators. Actually what you see is the diaphragm glued to a spacer which is glued on a stator. ;)
Can you take some pictures to show us? I don't understand what you meant by a large foil ring.
[Here's my answer]
I've damaged one of the diaphragms doing the operation, so I've decided to change both, or at least try to...
I've found mylar 2 microns. I still have to decide for the coating stuff.
Now, I have to figure how to unglue the two metal spacers that sandwiches both diaphragms. I'll try with a sharp knife, but maybe a solvent would be better ?
The diaphragms were really stuck to a stator on their complete surface. Once unstuck, tha stator was printed on the diaphragm.
I'll get back with some pictures...
